Sonar X3 cannot delete CC7

I'm using Sonar X3 Studio and when I move cursor back to an earlier section my bass and drums get louder.
I seem to have midi controllers CC7 volume where I can see the node in Piano Roll view for both bass and drum tracks, however I cannot erase them even in Event List view where the events do not show up.  I make sure I am viewing the correct track, but still cannot erase them.
 
I would appreciate assistance in resolving this.
 
Thank you,

Some soft synths, particularly those from Native Instruments, have a default setting that ties volume change to settings from the host software (Sonar).
 
For myself, and others, I would see the Battery 3 or Kontakt volume jump to a value I did not set, and even changing the volume settings for either Battery 3's volume, OR for the track's fader setting, it would always jump back to some other (almost always way louder) volume setting.
 
Sooooooo, after some digging around, I was able to determine that each of the Native Instruments' has a settings section, and there is a parameter for almost all of their modules where removing a check from a box tells that soft synth to NOT automatically respond to those CC volume message setting.
 
I do NOT know if the above is an available option for your synths, but it completely eliminated the issue for me, for all of the Native Instrument soft synths.
 
Please detail which synths are behaving like this for you, maybe we can collectively figure out if something similar to what happens to NI synths is at play here for you.

Perhaps CC7 is on the track as an envelope (automation) rather than MIDI events. Envelopes vs events is a strange idea at first to get used to. There is even a procedure to convert events into envelopes. But really, envelopes can be much more straightforward to edit.
 
If it's an envelope, you will see a faint line along the track, perhaps with nodes. You can edit the CC7 envelope by first accessing it in the drop-down list on the track header, the widget that usually says "clips". That highlights the envelop and allows you to edit or delete the nodes. You can also access the envelope by shift-clicking on the faint line.
